I have been slowly putting my used SMB into serviceable condition. With routine triple digit temps, the AC has become a priority. Blows cold in front and cool from Starcool unit.
It is a 1995 Starcool with R-134a. I read the manual and checked the sight glass. It has lots of air in it.
It is entirely possible that the unit has not been recharged since 1995.
First, is it a bad idea put in a couple of cans of R-134a and see if it holds pressure? Does the fact that it has air in it right now mean that it needs to be "cleaned" out first? If I go this route, how do I keep from overcharging?
Second, if I have it evacuated (and there are no leaks), what is a reasonable fee for the evacuation and recharge? I hate going in with no idea what it should cost.
PS: Here's a trip report. The story is about the Texas 200 sailing event but this was my first time out in the SMB. The SMB part of the trip was fine.....
